When power management is not enabled, or was not purchased, power levels
are set as follows:
• Pre-defined circuits – the power level is specified in the circuit
definition, along with data rate and other parameters.
• Remote-initiated calls – the power level is derived from System Setup,
using the Data or Video setting as appropriate
(see Initial System Settings.)
• Remote requests specifying a different data rate or FEC than that
shown in the System Setup – the power level from System Setup is
scaled to match the parameters requested.
When power management is enabled, the power level is determined by one of
the three methods described above, but each site will be limited to the TX
Power Levels defined for the site. Power Management will prevent calls from
being setup (site Call Blocking). When these calls will exceed the power
limitation of the Site. This is determined by:
• Site
• TX Gain
• HPA Power
• Control Channel Burst TX Power
